Connect to SharePoint Online with MFA using CSOM

Copper Contributor

I have the CSOM code below for trying to connect to SharePoint Online with MFA enabled:



$SiteUrl = ""

#Setup Authentication Manager
$AuthenticationManager = new-object OfficeDevPnP.Core.AuthenticationManager
$Ctx = $AuthenticationManager.GetWebLoginClientContext($SiteUrl)



I am encountering the following error: 


Error: Cannot find type [OfficeDevPnP.Core.AuthenticationManager]: verify that the assembly containing this type is loaded



I already have PnP SharePoint installed via "Install-Module PnP.PowerShell" so I am not sure what is wrong. For reasons, I cannot use the Connect-PnPOnline cmdlet.


How do I connect to SharePoint Online with CSOM if my account has MFA?

The latest iteration of the PnP.PowerShell module no longer includes this. You can try and replace "OfficeDevPnP.Core.AuthenticationManager" with "PnP.Framework.AuthenticationManager" instead.
I was able to by following this post but then get an error for "401 unauthorized":
